Gene Rains is a vibraphonist and leader of the Gene Rains Group, a jazz quartet from Hawaii that played a musical style known as Exotica. Rains' short career spanned the early to the mid 1960's and consisted of 4 LP recordings released on Decca Records and the Vocalion label.

These LPs were released during the golden era of Hawaiian and Exotica music and the Tiki culture in the United States. The Gene Rains Group repertoire featured popular Hawaiian and Polynesian Island melodies as well as popular American tunes of the era.

Gene Rains was "discovered" by the enormously popular Hawaiian crooner of the era, Alfred Apaka. At the time, Apaka was the talent director for the Hawaiian Village Hotel in Waikiki, Hawaii. Apaka recruited the Gene Rains Group to perform in the Shell Bar at the Hawaiian Village, which was THE hot spot for the Island's top performers, including Martin Denny and Arthur Lyman.

It was also Alfred Apaka who introduced Rains to Decca Records.Today, Rains is considered the third man of Exotica, behind Martin Denny and Arthur Lyman. Although he did not achieve the level of notoriety of Denny or Lyman, Rains' albums nonetheless are textbook examples of the style of Exotica.

With the resurgence of the Tiki culture in the late 1990's and into the early 2000's, Gene Rains' albums have become much sought after by collectors of the genre.
